.454 slugs in .457 Texan

[Greg_E]

Anyone that finds 457 ammo to be the correct size should consider this as an option. Buy 454 or maybe 452 ammo, clean it, and powder coat it. You should get right around 457 from the 454 bullets. That 0.003 of plastic might help them chamber too.

As far as Walther barrels being one of the best, there are a few of us with .510 barrels that would disagree.

have you tried Mr. Hollowpoint?

I started shooting 452 in my Texan last year and they chamber easier and are just as accurate as the 457 I dropped down from a 281gr NSA 457 to the 197gr NSA 452 and I'm now getting 980 fps where before I was getting around 910fps.

Very nice and information thank you for informing us all

When I got my Texan .457 early last year the only thing I could find was .452 sized pistol bullets. It shoots those just fine out to 147 yards which is the furthest target on my range behind the house. I have since scrounged up the components to cast and size my own .457 slugs. The .457 are more accurate but enough so to make the investment in casting worth it, don't know yet. I still need to chronograph these and see which one is getting me the best fpe for hunting later this year.

There was a thread either here on AGN or GTA where a fellow rented a chamber reamer to lengthen the chamber on his Texan and that helped with him being able to seat his bullets deeper and he said that helped with accuracy if I remember right.

By chance do you have the link or know where the article is that the guy rechambered his barrel or fix that a little bit I'm having a bit of the same issue where I have a really really tight bore waiting for some sizing dies or in smaller bullets to come in

I have since tested the 197gr .452 and they aren't consistently accurate past 50 yards I liked the speed but after further testing not accurate in my rifle it likes the longer slugs.

All you need is a throating reamer..PTG and Dave Manson Reamers make them..I have also used powder burner finish reamers in said airgun caliber and just run the reamer in far enough to cut throat.. You can rent throating reamers from reamerrentals.com...There is a hand finish chambering system from dave manson reamers that doesnt need a lathe.

weird, I was just wondering the same thing. .457 seem too tight, and I’m worried I’m losing velocity/accuracy. Have you put a chrono to it yet?

After putting some more of the .457's through the Texan I find that even if they seem tight, velocity and accuracy doesn't seem to be affected.

Llama I have since tested retested the 197gr NSA .452 slugs aren't as accurate as I thought in my Texan past 50 yards but I think that's because their a shorter slug, the .454 slugs I have sized down from .457

shoot just as accurate as my .457 slugs

I'm waiting for my sizing die to come in and I should have some results to post
